WILLIAM KROPP, OF MAPLE CITY, MICHIGAN.

WOOD-SAWING MACHINE.

T0 all whom t may concern.'

Be it known that I, WILLIAM Knorr, a citizen of the United States, residing at Maple City, in the county of Leelanau and State of Michigan, have invented new and useful Improvements in Wood-Sawing Machines, of which the following is a specification.

The invention relates to sawing machines, and more particularly to the class of wood sawing machines.

The primary object of the invention is the provision of a sawing machine of this character in which there is arranged a movable work supporting carriage, the latter being connected, through the medium of an equalizer, to the frame, so as to prevent the irregular movement of the carriage or the longitudinal displacement thereof, when the sawing machine is in operation.

Another object of the invention is the provision of a machine of this character in which the work to be sawed will be properly guided to the circular saw, without possibility of the displacement of the work, While the saw is in operation.

A further object of the invention is the provision of a sawing machine in which the frame thereof is provided with tracks, on which travels a forwardly and backwardly movable work supporting carriage, which is connected with the frame by means of an equalizer, so as to steady the .carriage and prevent the shifting of the same at either end, but causing it to move with uniformity and permit the work supported thereby to be presented to the saw in proper alinement therewith'.

A still further object of the invention is the provision of a saw of 'this character which is simple in construction, strong, durable, thoroughly reliable and efficient in operation, and inexpensive in manufacture.

With these and other objects in view, the invention consists in the construction, combination and arrangement of parts, as will be hereinafter more fully described, illustrated in the accompanying drawings, and pointed out in the claim hereunto appended.

In the drawings: Figure 1 is a side elevation of a sawing machine constructed in accordance with the invention. Fig. 2 is a top plan view thereof. Fig. 3 is a sectional view on the line 3--3 of Fig. 1. Fig. 4 is a vertical longitudinal sectional view through Specification of Letters Patent.

Application led June 6, 1911. Serial No. 631,573.

the machine. Fig.4 5 is a sectional view on the line 5 5 of Fig. 1.

Similar reference characters indicate corresponding parts throughout the several views of the drawings.

Referring to the drawings by numerals, the sawing machine comprises a main frame, including spaced parallel upper and lower longitudinal side beams 5 and 6, respectively, the same being spaced from each other by means of vertical posts 7, secured therebetween at intervals throughout the length of the beams, the lower side beams 6 being fixed to transverse brace ties 8 in any suitable manner, the latter designed to rest upon a floor or foundation. Extending from one bott-om side beam 6 to one top side beam 5, at opposite sides of the frame, are downwardly inclined brace bars 9 which strengthen the frame to increase the rigidity thereof.

Near one end of the frame and fixed transversely to the top side bars 5 are spaced parallel cross beams 10, on which is mounted a delivery deck or platform 11, the same extending transversely of the frame. At one side of t-he platform 11 and iXed to the cross beams 10 are bearings 12, in which is `iournaled a rotary shaft 13, the inner end of which has xedly connected thereto a circular saw 14, while the opposite end of the shaft has mounted thereon a fly wheel 15 and an adjacent band wheel 16, over which is adapted to be trained an endless band which is driven 4from any suit-able motive power for rotating the saw.

Mounted transversely of the frame and secured to the upper side beams 5 are spaced wide and narrow. gaged tracks 17 and 18, upon which is adapted to travel a work supporting carriage 19, having depending therefrom bearings 20, in which are journaled pairs of rollers 21 and 22, the rollers 22 being formed with at peripheries adapted to travel upon the wide gaged track 17, while the rollers 21 are formed in their peripheries with annular grooves 23 receiving the narrow gaged track 18, and are adapted to travel thereon. The carriage 19 has journaled therein, at intervals, rollers 24, on which is adapted to rest the timber to be cut, the carriage 19 being elongated and eX- tending longitudinally of the frame, so as to support logs or other timber of different lengths, and to present the same into position to be severed by the saw 14C When the carriage is moved in one direction on the tracks supported by the frame.

Journaled in the cross ties 8, at the bot-- tom of the frame, centrally between the bottom side beams 6, and disposed in longitudinal parallelism therewith, is a rocking equalizer, comprising a beam having fixed near opposite ends upwardly extending arms 26, the same being formed with eye terminals 27, in whichl areengaged links. 28, the. same being loosely connected in eyes 29,` formed on the plates 3 0 fixed to the, under face of the carriage 19, near the front side edge thereof, the equalizer being` adapted to steady theJ movement ovfj the carriage and to prevent the shifting thereof atk either end, but causing it to travel in` a uniform man ner. upon the tracks, without possibility of any irregular displacement, when supporting' timber to be cut by the saw.

The carriage, near the end; adjacent to the saw 14E, is provided with a hand hold 31, which is adapted to be engaged by an open. ator for moving. the. carriage forwardly andbackwardly on the main frame, when the vsaw is in operation, whereby the timber supsaw.

What is claimed is:

In a device of the kind described a combi nation with a supporting frame, and an elongated work supporting carriage` movable laterally thereof.; oi' means to urge said carriage in one direct-ion including a plurality of levers havingwidened lower ends forming elongated sockets, pivot means for supporting` said` levers intermediate their ends, links connecting said carriage and the upper ends of said levers, and a. weight member ixedly securedv in said elongated sockets whereby saidy levers are Co'mpelled to move in unison.

In testimony whereof I ailix my signature in presence of; two witnesses.v
